1. A method of controlling a force sensor system to define at least one button implemented by at least one force sensor, the method comprising:
receiving a force sensor input;
determining a gradient of the force sensor input; and
controlling the force sensor system based on the determined gradient;
wherein the method comprises:
comparing the determined gradient to a first re-calibration threshold and a second re-calibration threshold, wherein the first re-calibration threshold has a negative value and the second re-calibration threshold is set at a level higher than, or more positive than, that of the first re-calibration threshold; and
triggering a re-calibration of the force sensor system if the determined gradient crosses the first re-calibration threshold and the second re-calibration threshold, in that order.
